Description

Technical Field

[0001] This utility model relates to the technical field of wrenches, and in particular to an insulated explosion-proof wrench with an anti-slip rope buckle. Background Technology

[0002] A wrench is a common hand tool mainly used to rotate fasteners such as bolts and nuts. It tightens or loosens by applying torque and is widely used in many fields such as mechanical maintenance, building installation, and automobile repair. For example, open-end wrenches have a fixed opening size to fit specific bolt or nut specifications. They are simple in structure, low in cost, and suitable for operation in conventional spaces.

[0003] In practical use, existing insulated explosion-proof wrenches often slip out of hand due to limited space and complex operating postures in the work environment. This can be caused by uneven force, accidental collisions, or slippage due to sweaty hands. A slipped wrench may fall and injure personnel or equipment below. In flammable or explosive environments, sparks from a fall and impact with other objects could cause an explosion. In electrical work scenarios, if a slipped wrench comes into contact with live parts, it can not only damage the insulation and cause electric shock, but also cause short circuits, electrical faults, or even more serious accidents such as fires. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an insulated explosion-proof wrench with an anti-slip rope buckle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An insulated explosion-proof wrench with an anti-slip rope buckle includes a handle, one end of which is machined with a wrench mouth, and one end of which has a groove. A plate is fitted inside the groove, the plate being O-shaped and having an opening at one end. A ring is fitted onto one end of the plate, and a rope is connected to the ring. The rope is made of high-performance polyester, and one end of the rope is connected to a block. One end of the block has a groove. The handle and the wrench mouth are both made of aluminum bronze alloy. A bolt is threaded through one end of the block, and a portion of the bolt is located within the groove.

[0007] Preferably, one end of the handle is rotatably connected to a sleeve, one end of the sleeve has a pentagonal groove, and one end of the sleeve is connected to a hexagonal prism.

[0008] Preferably, a column is rotatably connected to one end of the plate, a stud is connected to one end of the plate, and a nut is threaded onto the column.

[0009] Preferably, a rubber pad is provided inside the second trough.

[0010] Preferably, the outer wall of the handle is covered with an anti-slip sleeve.

[0011] Preferably, one end of the rope is provided with a sponge pad.

[0012] Preferably, the anti-slip sleeve is made of nitrile rubber.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By using the combination of the ring, bolt, and rope, the ring is passed through the opening of the plate and placed on the plate. The rope is then wrapped around the wrist and inserted into the second groove and moved to adjust the distance between the block and the wrist. After adjustment according to individual needs, the bolt is tightened to press the rope into the second groove, forming a structure similar to a rope loop. The wrench is then hung on the user's wrist, which to some extent avoids the problem of sparks caused by the wrench colliding with other objects due to accidental drop, thus improving safety to a certain extent. At the same time, by adjusting the length of the rope passing through the second groove, it can be adapted to the wrists of different users, making it quite versatile.

[0015] 2. Through the fit between the sleeve, pentagonal slot, and hexagonal prism, the wrench at one end of the handle can be used to tighten hexagonal bolts or flat-head bolts. When it is necessary to tighten pentagonal bolts or internal hexagonal bolts, the pentagonal slot or hexagonal prism is placed on the outer wall of the pentagonal bolt or inserted into the inside of the internal hexagonal bolt, and then the bolt is tightened by rotating the sleeve. It can handle common hexagonal and flat-head bolts, as well as special bolts such as pentagonal and internal hexagonal bolts, without the need for frequent tool changes, thus improving operating efficiency to a certain extent.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figures 1 to 5 An insulated explosion-proof wrench with an anti-slip rope buckle includes a handle 1. One end of the handle 1 has a wrench head 2, which can be used to tighten hexagonal and flathead bolts. One end of the handle 1 has a groove 6, inside which a plate 7 is fitted. The plate 7 is O-shaped and has an opening at one end for easy insertion into the groove 6 and a ring 9. One end of the plate 7 is fitted with a ring 9, which is connected to a rope 8. The rope 8 is made of high-performance polyester, which has high strength, wear resistance, and tensile strength, and can withstand the tension during wrench use to prevent breakage. At the same time, the polyester material has good chemical stability and is suitable for various working environments. One end of the rope 8 is connected to a block 10. One end has a groove 11. Both the handle 1 and the wrench head 2 are made of aluminum bronze alloy, which has good insulation and explosion-proof performance. It is suitable for special working environments that are flammable, explosive, or electrically charged. To a certain extent, it can avoid the risk of electric sparks or electrical conduction caused by the material of the wrench, thus improving work safety. One end of the block 10 has a threaded bolt 12, part of which is located inside the groove 11. When the rope 8 is wrapped around the wrist and passes through the groove 11, turning the bolt 12 can press the rope 8 into the groove 11, thus fixing the rope 8. The rope 8 forms a structure similar to a rope loop, hanging the wrench on the user's wrist and preventing the wrench from falling to a certain extent. At the same time, this structure allows the length of the rope 8 to be adjusted according to the user's wrist size, adapting to different people and improving versatility to a certain extent.

[0024] In this embodiment, a sleeve 3 is rotatably connected to one end of the handle 1. A pentagonal groove 4 is provided at one end of the sleeve 3, and a hexagonal prism 5 is connected to the other end of the sleeve 3. The pentagonal groove 4 at one end of the sleeve 3 can accommodate pentagonal bolts, and the hexagonal prism 5 at the other end can accommodate hexagonal socket head cap screws. Combined with the wrench end 2 at one end of the handle 1, the wrench is compatible with various types of bolts such as hexagonal, flat-head, pentagonal, and hexagonal socket head cap screws, eliminating the need for frequent tool changes and improving operational efficiency to a certain extent. It also has a wide range of applicability. A column 13 is rotatably connected to one end of the plate 7, and a stud 14 is connected to the other end of the plate 7. A nut 15 is threadedly connected to the column 13. Rotating the nut 15 to thread it onto the stud 14 prevents the plate 7 from slipping out of the groove 6 and also prevents the ring 9 from slipping out. When not using the wrench, the operation can be reversed to disassemble the plate 7 and rope 8 for maintenance or replacement. A rubber pad 16 is provided inside the groove 11 to prevent the bolt 12 from directly rubbing against the rope 8, while increasing the friction with the rope 8 and improving clamping stability. An anti-slip sleeve 18 is fitted onto the outer wall of the handle 1, which enhances friction during gripping and further prevents slippage. A sponge pad 17 is provided at one end of the rope 8 to prevent excessive friction or pressure on the skin, improving comfort to some extent. The anti-slip sleeve 18 is made of nitrile rubber, which is elastic and fits tightly against the outer wall of the handle 1, preventing loosening; at the same time, its high surface friction maintains good anti-slip performance even in wet environments, further enhancing grip stability.

[0025] The working principle of this embodiment is as follows: Before operation, precautions must be taken to prevent the wrench from slipping off the wrist. First, rotate the column 13 to enlarge the opening at one end of the plate 7, and then fit the plate 7 into the groove 6. Next, pass the ring 9 through the opening of the plate 7 and fit it onto the plate 7 at a suitable position. Rotate the nut 15 to connect it with the stud 14, restricting the rotation of the column 13 and sealing the opening at one end of the plate 7. Then, loop the rope 8 around the wrist and insert it into the groove 11. Pull the rope 8 to adjust it to a suitable length, and tighten the bolt 12 to secure the rope 8. The rope 8 forms a structure similar to a loop, allowing the wrench to be hung on the user's wrist. This helps to prevent the wrench from falling due to accidental factors and colliding with other objects to generate sparks, which could even cause an explosion in a flammable environment. Select the appropriate working end according to the actual operational needs. To tighten hex bolts or flathead bolts, use the wrench 2 at one end of the handle 1. Directly turning the handle 1 will rotate the hex bolt or flathead bolt. When dealing with pentagonal bolts, place the pentagonal groove 4 at one end of the sleeve 3 onto the outer wall of the pentagonal bolt. To handle socket head cap screws, insert the hexagonal prism 5 at one end of the sleeve 3 into the socket head cap screw, and then rotate the sleeve 3 to tighten the pentagonal bolt and socket head cap screw.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
